Abstract

The invention provides a network-based video editing system, in which video clips are made available on demand to servers located in a plurality of spatially separated zones linked only via the network. In order to ensure that cautionary or advisory information contained in signs or signals ('tags') associated with certain video material is retained during transfer between servers in different zones, the invention provides that new tags associated with video material in any zone are broadcast generally to all other zones. Only tags associated with video information currently stored in any zone are retained in that zone, but all tags associated with information copied from a first zone to a second zone are supplied to the second zone. In a preferred system, the video material is time-stamped to permit conflicts in the content of multiple tags relating to the same video material to be resolved by making the most recent prevail. The invention also provides a method for operating such a system.
